摘要： The present invention relates to an apparatus for measuring the degree of vacuum of a multistage vacuum heat-insulating member and to a measurement method using same. To this end, the present invention provides an apparatus for measuring the degree of vacuum of a multistage vacuum heat-insulating member comprising: a chamber in which a plurality of vacuum heat-insulating members are accommodated and which forms a sealed space; a shelf arranged within the chamber so as to support the plurality of vacuum heat-insulating members in a plurality of layers; a displacement sensor for sensing the displacement of each outer shell of the vacuum heat-insulating members stacked on the shelf; and vacuum means connected to the chamber so as to regulate the pressure of the internal space of the chamber. In addition, a method for measuring the degree of vacuum of a vacuum heat-insulating member, including a core and an outer shell covering the core, comprises placing and sealing a plurality of vacuum heat-insulating members into the internal space of a chamber, evacuating the internal space of the chamber, and measuring the displacement of the outer shell of the vacuum heat-insulating member caused by the variation in pressure, to thereby verify whether or not the vacuum heat-insulating member is damaged.
